The viral genus Henipavirus includes two highly virulent zoonotic viruses of serious public health concern. Hendra henipavirus and Nipah outbreaks are restricted to Australia Southeast Asia, respectively. comprises mostly bat-borne viruses, but exceptions have already been described as novel with rodents shrews reservoir animals. In the Americas, scarce evidence supports circulation these viruses. this communication, we report a henipa-like virus from opossums (Marmosa demerarae) forest...
Dengue virus serotype 2 (DENV-2) is responsible for dengue epidemics on a global scale and associated with severe cases of the disease. This study conducted phylogenetic investigation DENV-2 isolates from 2017 to 2021 originating northern states Brazil. A total 32 samples were analyzed, including 12 Acre, 19 Roraima, one Tocantins. Only lineage Asian-American genotype cosmopolitan observed: Lineage 1, (connection Puerto Rico); 5, Peru). Our results provide important data regarding DENV...
From 1988-2023, Pará accounted for the highest proportion of deforestation among all states in Brazilian Amazon. Specifically, 57.20 % territory Santa Bárbara municipality was deforested as 2023. Since 2017, Hantaviridae family has included viruses identified nonrodent vertebrates, such mobatviruses (from moles and bats). In current metagenomic analysis a pool multiple organs Carollia brevicauda bat, we obtained sequences three segments previously described Buritiense virus (BURV); to date,...
The viral genus Henipavirus includes two highly virulent zoonotic viruses of serious public health concern. Hendra henipavirus and Nipah outbreaks are restricted to Australia Southeast Asia, respectively. comprises mostly bat-borne viruses, but exceptions have already been described with novel having rodents shrews as reservoir animals. In the Americas, scarce evidence supports circulation these viruses. this communication, we report a henipa-like virus from opossums (Marmosa demerarae)...
Viruses of the Lyssavirus genus are classified into several genotypes (GT1 to GT7), which only GT1 (classic rabies virus-RABV) has a cosmopolitan distribution and circulates in Brazil. is subdivided antigenic variants (AgV) maintained independent cycles with narrow host range distinct geographic distributions, namely, AgV1 AgV2 found dogs, AgV3 vampire bats Desmodus rotundus, AgV4 AgV6 non-hematophagous Tadarida brasiliensis Lasiurus cinereus, common variant marmoset (Callithrix jacchus),...
As part of a continuous effort to investigate the viral communities associated with wild mammals at human–animal interface in an Amazonian metropolitan region, this study describes detection novel rodent-borne arterivirus. A sample containing pooled organs Oecomys paricola was submitted RNA sequencing, and four sequences taxonomically assigned as related Arteriviridae family were recovered, corresponding almost complete genome nearly 13 kb summed. In phylogenetic analysis standard domains...
The largest outbreak of sylvatic yellow fever virus (YFV) in eight decades was recorded Brazil between 2016-2018. Besides human and NHP surveillance, the entomo-virological approach is considered as a complementary tool. For this study, total 2904 mosquitoes Aedes, Haemagogus Sabethes genera were collected from six Brazilian states (Bahia, Goiás, Mato Grosso, Minas Gerais, Pará, Tocantins) grouped into 246 pools, which tested for YFV using RT-qPCR. We detected 20 positive pools 5 1 Bahia,...
O vírus linfotrópico de células T humanas (HTLV) (Retroviridae: Deltaretrovirus) possui características zoonóticas por derivar linhagens símias (STLV) em função provavelmente do contato interespécie, com quadro clínico caracterizado linfomas, mielopatia, linfocitose e doenças neurológicas leves. desenvolvimento estudos epidemiológicos permitem assim compreender a distribuição atual das diferentes vírus, principalmente partir da utilização metodologias ferramentas biologia molecular,...
Loreto virus (LORV) is an insect-specific classified into the proposed taxon Negevirus. It was originally described in Iquitos, Peru, 1977. Here, we describe three novel LORV genomes obtained from isolates of pooled samples Trichoprosopon digitatum, Aedes (Ochlerotatus) fulvus, and Limatus durhamii collected Ilhéus—Bahia, 2014. Samples were submitted to RNA sequencing on Illumina platform recover genome. The presented, average, 81.5% nucleotide identity 92.6% global amino acid with reference...

Dengue virus serotype 2 (DENV-2) is responsible for dengue epidemics on a global scale and recognized being associated with severe cases of the disease. This study conducted phylogenetic investigation DENV-2 in Northern region Brazil. isolates from 2017 to 2021, originating Brazilian states, were selected. Only one lineage (I) Asian-American genotype (5) cosmopolitan observed. All sequences used this segregated into paraphyletic subgroup aligned an American clade. These results indicate...
